BuyGreen: Office & Desk Chairs

Anyone that sits at a desk or in a chair for part or all of their work knows that what you sit in really matters. Not only does it affect how comfortable and productive you are, but poor seating can have some pretty negative long-term health effects, limiting your ability to earn the green.

The chairs you'll find here are designed to help you feel better at work, not only providing relief to your arching back, but relieving some of the pressure your office puts on the environment. Choose from lots of colors and fabrics to fit your budget and style; since they've all been designed with sustainability in mind -- spanning the spectrum from infinitely adjustable to so smart that it adjusts to you -- each one can make a case for being the last task chair you'll ever have to buy. Hit the jump to start sitting pretty.
